I'm working with a "Pro" version of this plugin that was purchased directly from your website not even a month ago.

I'm not sure how the paid "Pro" plugin is different from what you're offering here for free and would also like to see that clarified on the plugin description page on wordpress.org, as well as on your site.

Issue 1:

When this plugin is activated, if it's checked to "boost" a specific page, and then unchecked later, the all the plugin content boxes do not disappear after being removed from a page.

Basically, it makes every edit page 2 to 3 times longer -- even when the plugins features are not in use on that page. It's an issue, especially when there are already other critical plugins bulking up edit pages.

How do I make it disappear when not in use (when settings are off for a specific page) ?

Issue 2:

Also, it seems to have a conflict with woocommerce. When activated, the product names disappear -- meaning I cannot edit the products. It happens only when SEO Booster is activated.

"When this plugin is activated, if it's checked to "boost" a specific page, and then unchecked later, the all the plugin content boxes do not disappear after being removed from a page."

What do you mean with checked to boost a specific page and where did you define that? And what does make the edit page longer? Do you mean the meta box below the editor? This meta box can be closed easily, just like every other meta box in WordPress.

About Woocommerce. I have no idea what that could be. I working on an onlineshop with woocommerce myself and SEO Booster is activated there too and I don't have any conflicts at all.
